Event Information

  • The google.cloud.run.v2.Services.DeleteService event in GCP for CloudRun indicates that a service has been deleted in the Cloud Run environment.
  • This event signifies that the specified service, which is a containerized application running on Cloud Run, has been removed from the platform.
  • It is important to note that deleting a service will permanently remove all associated resources, including the container image, deployment, and any allocated resources such as CPU and memory.

​
Examples

  1. Unauthorized deletion: If security is impacted with google.cloud.run.v2.Services.DeleteService in GCP for CloudRun, it could mean that unauthorized individuals or entities are able to delete services without proper authentication or authorization. This could lead to the accidental or intentional deletion of critical services, resulting in service disruptions or data loss.

  2. Lack of audit trail: Another security impact could be the absence of an audit trail for service deletions. Without proper logging and monitoring mechanisms in place, it becomes difficult to track and investigate any unauthorized or suspicious deletions. This can hinder incident response efforts and make it challenging to identify the root cause of security incidents.

  3. Inadequate access controls: If security is impacted with google.cloud.run.v2.Services.DeleteService, it could indicate that there are weaknesses in the access controls governing service deletion. This could mean that users or roles have excessive permissions, allowing them to delete services they should not have access to. It is crucial to ensure that access controls are properly configured and regularly reviewed to prevent unauthorized deletions and maintain the principle of least privilege.

Remediation

​
Using Console

  1. Enable VPC Service Controls:

    • Go to the GCP Console and navigate to the Cloud Run service.
    • Select the specific Cloud Run service you want to remediate.
    • Click on “Edit and Deploy New Revision” to access the service settings.
    • Scroll down to the “Security” section and click on “Enable VPC Service Controls”.
    • Follow the prompts to set up VPC Service Controls for the Cloud Run service.

  2. Implement Identity and Access Management (IAM) Roles:

    • Go to the GCP Console and navigate to the Cloud Run service.
    • Select the specific Cloud Run service you want to remediate.
    • Click on “Edit and Deploy New Revision” to access the service settings.
    • Scroll down to the “Security” section and click on “Show Info Panel”.
    • Click on “Add Member” to add the appropriate IAM roles to the service.
    • Assign the necessary roles to the relevant users or service accounts.

  3. Enable Cloud Audit Logging:

    • Go to the GCP Console and navigate to the Cloud Run service.
    • Select the specific Cloud Run service you want to remediate.
    • Click on “Edit and Deploy New Revision” to access the service settings.
    • Scroll down to the “Security” section and click on “Show Info Panel”.
    • Enable the “Cloud Audit Logging” option to start logging all activity related to the Cloud Run service.
    • Configure the desired log retention period and destination for the logs.

​
Using CLI

  1. Enable VPC Service Controls for Cloud Run:
  • Use the following command to enable VPC Service Controls for Cloud Run: 
    gcloud services vpc-peerings connect \
--service=servicenetworking.googleapis.com \
--network=projects/[PROJECT_ID]/global/networks/[NETWORK_NAME]
  1. Implement Identity and Access Management (IAM) roles and permissions:
  • Use the following command to grant the necessary IAM roles to the appropriate users or service accounts: 
    gcloud projects add-iam-policy-binding [PROJECT_ID] \
--member=[MEMBER] \
--role=[ROLE]
  1. Enable Cloud Audit Logging for Cloud Run:
  • Use the following command to enable Cloud Audit Logging for Cloud Run: 
    gcloud logging sinks create [SINK_NAME] \
storage.googleapis.com/projects/[PROJECT_ID]/buckets/[BUCKET_NAME] \
--log-filter='resource.type="cloud_run_revision"'

​
Using Python

To remediate the issues mentioned in the previous response for GCP CloudRun using Python, you can follow these steps:

  1. Implement proper authentication and access controls:

    • Use the Google Cloud SDK and authenticate with a service account that has the necessary permissions to access and manage CloudRun resources.
    • Use the google-auth library in Python to authenticate requests to the CloudRun API.
    • Set up fine-grained IAM roles and permissions to restrict access to CloudRun resources based on the principle of least privilege.

  2. Enable logging and monitoring:

    • Use the google-cloud-logging library in Python to enable logging for your CloudRun services.
    • Configure log sinks to export logs to a centralized logging solution like Stackdriver or Cloud Logging.
    • Set up monitoring and alerting using tools like Cloud Monitoring or Prometheus to proactively detect and respond to any anomalies or issues in your CloudRun services.

  3. Implement secure communication:

    • Use HTTPS for all incoming requests to your CloudRun services by configuring SSL certificates.
    • Implement proper input validation and sanitization to prevent common security vulnerabilities like SQL injection or cross-site scripting (XSS).
    • Use the google-auth library in Python to authenticate and authorize requests to any external services or APIs that your CloudRun services interact with.

Please note that the provided steps are high-level guidelines, and the actual implementation may vary based on your specific requirements and the structure of your Python code.
